FLOOR-SCRUBBING MACHINE.

Specification of Letters Patent.

Patented net. 5, rate.

Application filed December 9, 1916. Serial No. 135,933.

To all whom it may concern."

Be it known that I, LEON LEWANDOWSKI, citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Floor-Scrubbing Machines, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to floor scrubbing machines, sh own in the accompanying drawings and more particularly pointed out in the following specification and claim.

One object of the invention is to provide a floor scrubbing machine in which there is provided a main roll embodying a plurality of yieldable disks arranged side by side to form a yieldable body and with which cooperates a roll in yieldable driving contact with the main roll and provided with end pliiites to overlap the extremities of the main ro Other advantages and improvements will hereafter appear.

In the drawings accompanying this specification- F igure 1, is a plan view of the machine.

Fig. 2, is a side elevation of the same.

Fig. 3, is a front elevation of the machine with parts broken away.

Fig. 4, is a longitudinal vertical section through the machine.

Fig. 5, is a fragmentary detail showing the means employed for maintaining the wringing roll in contact with the mopping or wiping roll, whereby the dirty water may be discharged into the receptacle provided to receive it.

Referring now to the letters of reference placed upon the drawings,

A, denotes the frame of the machine, B, indicates a water tank, provided with a closure cap B. U, is a pipe leading therefrom under control of a valve D. E, is a transverse fitting connected with the pipe C, having a plurality of apertures (not shown) on its underside through which water may be discharged upon the floor. F, denotes a pair of forward traction wheels for supporting the machine mounted upon a transverse shaft f, journaled in the frame. Gr, is a driving gear mounted upon the shaft 7; H, is a gear in mesh with the driving gear G, mounted upon the upper transverse shaft 7t, journaled in the frame of the machine. I, I, are beveled gears mounted in spaced relation upon the shaft it. J. J, are beveled gears driven by the gears I, 1, respectively mounted on the vertical shafts J, J, journalcd in the frame. K, K, are crossed scrubbing brushes mounted on the vertical shafts J, J. J 2 is a spring sleeved on the shafts J, adapted to force the brushes into close contact with the floor. L, designates a pair of rear traction wheels mounted upon the transverse shaft Z, on which is carried the driving gear M. N, is an intermediate gear in mesh with the gear M, and the gear 0, mounted upon the upper transverse shaft 0 journaled in the frame. P, P, are beveled gears mounted upon the shaft 0 respectively in mesh with the beveled gears Q, Q, carried by the vertical shafts Q, Q, journaled in the frame of the machine. R, R, are crossed scrubbing brushes mounted on the vertical shafts Q, Q ;-and R, R, are springs sleeved upon the shafts Q, Q, adapted to force the brushes into close contact with the floor. S, designates a mopping roll mounted upon the transverse shaft S journaled in the frame, and is preferably constructed of a plurality of felt or other disks S sleeved upon the shaft. T, is a gear on the shaft S, in mesh with the driving gear M. U, is a wringing roll mounted upon the transverse shaft U, journaled in sliding boxes U supported by the frame of the machine. The roll U has end plates which overlap the end disks of the mopping roll as clearly shown in Figs. 2 and l. V, indicates a spring engaging the journal boxes U and the frame of the machine, the action of which serves to force the roll U, into wringing or driving contact with the mopping roll S. W, denotes a discharge tank to receive the dirty water wrung from the mopping roll S, by the roll U. X, designates a handle journaled in the frame of the machine by which. it may be manually pushed over the floor.

Having indicated the several parts by reference letters the construction and operation of the device will to readily understood.

Hot or other water is first supplied to the water tank B, through the opening closed by the filler cap 38', the water being preferably "charged with soap or some suitable cleaning agent. Thevalve D, isthen'adjfisted to 'controlthe volume of- W'ater-fdischarged through the 'perforations in the 5 transverse fitting E, onto the floor to be scrubbed. The machine is then manually pnshejd forwardand back by means oftlie handle -X, "thusrotating the' i'espect ive brushes K, K, and R li thronghthe inter- 10 mediate gearing driven by the traction is,,gea edite-r ta intlles m d ec ion- F ggp ie s at g is ggtent gaya'qc;Detained flori jtve cents; sea-0th, by, 8.

close wrmging contact by the springs V;

1 the dirty water discharged being delivered into thetankWV, from which it is subseq ently removed.

Having thus described my invention, What I claim is In combination, a main r011 embodying a pll lr alityof yield-able disks arranged side by side to form a yieldable body, and a cooperating roll inyieldable driving contact iyvithtthema-in roll and provided with end ,plates, to overlap the extremities of the main troll.

Intestimony whereof, .I ,sign this specification in the presencetof.two Witnesses.
